Abstract (en)
[origin: EP2876876A2] An image projection apparatus (1) includes a projection unit (31) that projects a pattern image on a projection surface; an image capturing unit (44) that captures the projected pattern image; and a corrector (51) that corrects the captured image so that an imaging distortion caused due to image capturing and a projection distortion caused due to projection are corrected. The projection unit (31) projects the corrected captured image at a predetermined position on the projection surface.
